Did you run your 12+ to the battery? did you supply a sufficient ground of least 2x the size of the power lead?..did you hook up to the amp turn on lead and NOT the power antenna? model numbers of radio and amp would really be helpful...my email is troublerst@hotmail.com send me specifics and we will work it out

go into the menu screen on the pioneer unit and go to setting if you have a loud function there turn it on.... if that doesn't activate the amp ...(did you hook up the blue wire from pioneer deck to amp and run it threw the car to the amp)..if no than your pioneer deck does not realize there is an amp present in system....... if yes scroll threw menu till you see audio look for Sub Woofer or Amp you may even have a button on pioneer deck marked SW go press it and turn amp to on this will provide signal from pioneer unit to amp if this doesn't work other thing could be you hooked RCA to AUX input (but if you have a SW for RCA plugs on back of unit make sure the RCA wires are in it) the loud or SW button should activate it (if there is only F and R for RCA plugs on back of unit use R hope this helps)

check for any loose connections at the fuse block or a loose fuse
using an ohm meter would help
check the harness on the back of the radio for loose connection
bad igntion switch, again an ohm meter would help !
what type vehicle ?

your amp turn on is hooked to the power antenna wire. Swap the blue wires and youll be good to go. Since the power antenna is not needed, when the radio goes off tuner, the 12V signal is turned off. and your amplifier will also then lose its remote turn on.
Reverse the 2 blue wires.

does the amp turn on when the deck is turned on ? is the ground hooked to the body of the car to bare metal w/out paint ect ...under it ? you may want to take it to a installer there are many things it could be they can also test your rca outputs if thats the problem. curcuit city is a cheap place to have your equipment tested if you live close to one

The system remote control is usually a blue wire on your decks harness and it is for an amplifier for a sub or other speakers. It sends power to the subs amp when the deck is turned on. You may need to find the wires coming off the antenna and splice them into the red power switching wire 12v on you decks wire harness. Good luck

Hi
Your problem is almost defenetly that one speaker is hooked up with reversed polarities, making one speaker cancel out some vibrations of the other speaker.
So get the wiring phase checked again, its ethier this or a fauly cable.
Good luck.
